Abstract

OBJECTIVE

To analyze the clinical and sonographic variables that predicts the success of labor induction.

STUDY DESIGN

We studied the Bishop score, cervical length and parity in 196 pregnant women in the prediction of successful vaginal delivery within 24 h of induction. Logistic regression and segmentation analysis were performed.

RESULTS

Cervical length (odds ratio (OR) 1.089, P<0.001), Bishop score (OR 0.751, P=0.001) and parity (OR 4.7, P<0.001) predict the success of labor induction. In a global analysis of the variables studied, the best statistic sequence that predicts the labor induction was found when we introduced parity in the first place. The success of labor induction in nulliparous was 50.8 and 83.3% in multiparous women (P=0.0001).

CONCLUSIONS

Cervical length, Bishop score and parity, integrated in a flow chart, provide independent prediction of vaginal delivery within 24 h of induction.

摘要

目的

分析预测引产成功的临床及超声变量。

研究设计

我们研究了196名孕妇的 Bishop 评分、宫颈长度和产次，以预测引产24小时内阴道分娩成功情况。进行了逻辑回归和分段分析。

结果

宫颈长度（比值比（OR）1.089，P<0.001）、Bishop 评分（OR 0.751，P=0.001）和产次（OR 4.7，P<0.001）可预测引产成功。在对所研究变量的综合分析中，当首先引入产次时，发现了预测引产的最佳统计序列。初产妇引产成功率为50.8%，经产妇为83.3%（P=0.0001）。
